Global server freeze - 1.19.2 Modded with CurseForge (modpack steampunk)

[Th3Fall3nAng3l]

Hello guys !

First, I might make some mistakes in terms of words... I'm french so go easy on me 😂

I'm having an issue with my docker server rn.

To give some context, I wanted to create a server on which I could play with my friends while using mods. I'm used to running a lot of things on docker so I said "why not use a docker container".

So I started to use the documentation to get everything I needed to create my docker_compose file. Me and my friends chose to use the modpack "steampunk" on the 1.19.2 version. And to automate things (and because it's easy) I used auto-curseforge to automatically download all mods. Everything went well (everything but some dependency needed on the client side...) and the server started well ! I still saw some errors on the start of the server (some red lines 😅) but the server still started.

After playing for five minutes, the server "freezed" for 30s without giving any logs... I've tried to generate a lot of chunks to see if it was related to the simulation distance and the rendering distance but it wasn't freezing (using elytras and rockets...) so I'm totally lost, mostly due to a lack of experience... This issue happen periodically, making the game unplayable... It also happens when I'm alone on the server so it's not related to the number of players connected.

The first image I give is the only "repercussions" I can see on the server when the freeze started. The CPU utilisation drastically drops from 70% (of utilisation) to 0%... I don't understand how...

I also give the logs I got when the freezing happened, the only thing special this time is that the server detected the lag and wrote it in the logs.

Thanks in advance for every hint I can get from you guys !

The logs I am talking of (sorry I don't know how to integrate code to the discussion) :
